NoMethodError (undefined method `page' for #<Broadcast:0x00000003fd9320>):

Question

I am a bit new to rails, and one of my task is migrating a rails 2.1 app to 3.2. Start steb by step, first 2.1 to 2.3 rails, and now to 3.2.

Can't use bundle or gem file but I have all the gems I need installed.

My issue is now converting will paginate methods.

I had my requires in an /config/initializer/load.rb in this order

require 'rails' require 'rails/all' require 'prototype-rails' require 'will_paginate'

The libs are loaded with success.

But when I try to use paginate in my source I get this error.

NoMethodError (undefined method `page' for #<Broadcast:0x00000003fd9320>):
  app/controllers/broadcasts_controller.rb

my controller is has this code:

@broadcasts = Broadcast.page(params[:page] || 1).select(select_clause).order( order_clause)

the broadcast model is something like

class Broadcast < ActiveRecord::Base
  extend PhoneNumberFormatValidation
  ...
end

I try to put the "require will_paginate" just before my controller but it didn't work. If I run rails console

[user1@virtual-rh6x64 web]$ rails c
irb(main):001:0> require 'will_paginate'
=> false

I don't understand why can't find will paginate methods. Does he work with ActiveRecord::Base?

my gems are:

Answer 1

Try using

 require 'will_paginate/active_record'

To load specific childs you may need to track down what childs will_paginate loads in a normal setup through Bundler.. because in that way it doesn't require loading these childs
